SensorsTemperatures returns 0 values for all sensors on darwin arm64 (M1)

[splmatto]

Describe the bug
the temperature value of each TemperatureStat object in the array returned by host.SensorsTemperatures() is 0 on an M1.

To Reproduce

package main

import (
	"encoding/json"
	"fmt"
	"github.com/shirou/gopsutil/v3/host"
)

func main() {
	tstat, _ := host.SensorsTemperatures()
	serialized, _ := json.Marshal(tstat)
	fmt.Printf("%s", string(serialized))
}

Here's the output:

  }
]

Expected behavior
Return valid temperature sensor data for one or more of the sensors.

Can confirm also happens on M2 Pro,

[ { "sensorKey": "TA0P", "sensorTemperature": 0 }, { "sensorKey": "TA1P", "sensorTemperature": 0 }, { "sensorKey": "TC0D", "sensorTemperature": 0 }, { "sensorKey": "TC0H", "sensorTemperature": 0 }, { "sensorKey": "TC0P", "sensorTemperature": 0 }, { "sensorKey": "TB0T", "sensorTemperature": 0 }, { "sensorKey": "TB1T", "sensorTemperature": 0 }, { "sensorKey": "TB2T", "sensorTemperature": 0 }, { "sensorKey": "TB3T", "sensorTemperature": 0 }, { "sensorKey": "TG0D", "sensorTemperature": 0 }, { "sensorKey": "TG0H", "sensorTemperature": 0 }, { "sensorKey": "TG0P", "sensorTemperature": 0 } { "sensorKey": "TH0P", "sensorTemperature": 0 }, { "sensorKey": "TM0S", "sensorTemperature": 0 } { "sensorKey": "TM0P", "sensorTemperature": 0 }, { "sensorKey": "TN0H", "sensorTemperature": 0 }, { "sensorKey": "TN0D", "sensorTemperature": 0 }, { "sensorKey": "TN0P", "sensorTemperature": 0 }, { "sensorKey": "TI0P", "sensorTemperature": 0 }, { "sensorKey": "TI1P", "sensorTemperature": 0 }, { "sensorKey": "TW0P", "sensorTemperature": 0 } ]

Is there progress in solving the problem?

[davidnewhall]

Same problem with v4. Macs have no temperatures. Test code:

package main

import (
	"encoding/json"
	"fmt"
	"github.com/shirou/gopsutil/v4/sensors"
)

func main() {
	tstat, _ := sensors.SensorsTemperatures()
	serialized, _ := json.MarshalIndent(tstat, "", " ")
	fmt.Printf("%s", string(serialized))
}

Partial output (the rest looks like the original post):

[
 {
  "sensorKey": "TA0P",
  "temperature": 0,
  "sensorHigh": 0,
  "sensorCritical": 0
 },
 {
  "sensorKey": "TA1P",
  "temperature": 0,
  "sensorHigh": 0,
  "sensorCritical": 0
 },

@Girbons - any chance you know how to fix this? <3

I'll take a look why it isn't working on arm
